In order to control NOx emissions the Texas Commission on Environmental Quality (TCEQ) has enacted Small Combustion Sources Chapter 117 subchapter D, which regulates NOx emissions from small sources.
We have performed environmental testing work throughout the continental United States and internationally in places such as Canada, Mexico, and Europe. Most of our projects have been for compliance with federal and state regulations, and were performed under the observation of relevant regulatory personnel. Our clients are both large and small and we treat all projects with the same urgency and attention to detail. Our clients include companies such as Cabot Corporation, Hoechst Celanese, Dow Chemical, DuPont, GE Plastics, Exxon Chemical, ARCO, 3M, Eastman Chemical, Georgia Pacific, Entergy, and many others.
